SPRING-WHEEL.

Specification of Letters Patent.

Patented Jan. 13, 1914.

Application filed June 1, 1910. Serial No. 564,420.

To all whom it may concern:

Be it known that I, ALBERT S. KINNEY, a citizen of the United States,residing at Middletown, in the county of Butler and State of Ohio, haveinvented new and useful Improvements in Spring-l/Vlreels, of which thefollowing is a specification.

This invention relates to spring wheels and more particularly to spokesused in con nection therewith, the object of the invention being toprovide a spoke which is resilient lengthwise of its body so that allthe advantages of a pneumatic tired wheel may be obtained in a wheelusing spokes of this character.

A further object of the invention is the provision of a novel spokewhich may be reversed in its connection between the hub and felly.

Further objects of the invention will appear as the following specificdescription is read in connection with the accompanying drawing whichforms a part of this specification, and in which:

Figure 1 is a detail elevation of a wheel showing my improved spokesecured. therein. Fig. 2 is an enlarged detail sectional view on theline 2-2 of Fig. 1. Fig. 3 is a detail plan View of the folly blank.

Referring more particularly to the drawing 1 represents the hub whichcomprises the side plates 2 and 3 and the axle boxing The felly is shownat 5 and the wheel tire at 6.

The spokes which are used in connection with the hub and felly abovementioned comprise a piston cylinder 7 provided at its outer end with atransverse head 8 having a central aperture 9 to receive the pivotalbolt 10 which secures the cylinder to the folly band 11. This band issecured to the felly 5 by bolts 12 and has interposed between itspivoting ears suitable shock absorbing washers 13. Surrounding the baseof the cylinder 7 and resting upon the head 8 is a collar 1-1 having avertical annular flange 15 which forms a socket for the end of thehollow wooden section 16 of the spoke. A suitable washer 17 isinterposed between the end of the spoke and the collar 14;. A similarcollar 18 is threaded in the upper end of the cylinder 7 and is providedwith a downwardly extending flange 19 which forms a socket adapted toreceive the upper end of the wooden section 16 and a similar washer 20is interposed between the end of the wooden section and the collar.

Reciprocally mounted within the cylinder is a plunger 21 having threadedupon its upper end a collar 22 with a depending flange 23 correspondingwith a similar flange 24: on the collar 18. The collars 22 and 1-8 andtheir flanges 23 and 24: form a receptacle for a spiral spring 25 whichsurrounds the plunger 21 and normally keeps its lower end raised in thecylinder. The spring 25 of each spoke is suitably connected to thecollars'so that it may be active at all times whether extended when atthe top of the wheel or depressed when at the base. The plunger 21 has atransverse head 26 similar to the head 8 and is apertured at 27 toreceive the pivoting bolt 28 which passes through opposite registeringapertures 29 in the side plates 2 and 3 of the hub. As shown in thelower connection of the spoke. the head 26 has interposed between it andthe side plate suitable shock absorbing washers 30. It will be noticedthat the heads 26 and 8 are exactly similar and by simply disconnectingthe bolts 28 and 10, the spoke may be reversed.

Having thus described the invention, what is claimed is In a wheel. thecombination with a hub and felly, of a continuous band passing aroundinside of the folly and having a plurality of pairs of integral parallelears extending inwardly from the band, spokes interconnecting the huband i'ielly each co1n-' prising ahead pivotally connected between a pairof said cars, a closed cylinder integrally connected with the head, asecond head pivotally connected to the hub, a plunger section rigidlycarried by said second head and adapted to work in said cylinder, aflanged collar carried by the cylinder, a second flanged collaradjustably mounted on the plunger and a spring interposed between saidoollars and surrounding the plunger.

In testimony whereof I afiix my signature in presence of two witnesses.

ALBERT S. KINNEY.
